Educating trainees on fMRI interpretation may be more effective using combined task activation display (CTAD) rather than displaying a single task at a time, reported researchers of a March 29 study published in Clinical Imaging.

To improve transparency, black box algorithms are increasingly being built with functions that explain their diagnostic findings. But a recent NPR report examined how this isn’t always effective, and why a different approach to creating algorithms may be the answer.

Using contrast agents to enhance CT scans is an established risk factor for kidney injury in those at risk for renal complications, according to a March 23 NPR report, but the research that drove that conclusion years ago might be unbalanced.

A U.S. radiologist with a long, distinguished career that launched after a remarkable move from Korea has caught the eye of a National Public Radio affiliate in Buffalo, New York.

A study published in Radiology on March 26 suggests rapid short-pulse ultrasound is as effective—and maybe more so—than standard and long-pulse therapy for delivering drugs across the blood-brain barrier.

Researchers have established normal ranges of bone density in a part of the lumbar spine that is routinely imaged incidentally. Their primary aim is to equip radiologists with data that can be referred to when reading chest and abdominal CTs so the reader can opportunistically cross-screen for osteoporosis and check for compression fractures.

Going by a small study published online March 22 in European Radiology, biplanar digital radiographs of the hip joint reconstructed in 3D as well as 2D are sufficiently comparable on coverage assessments with similarly rendered CT scans to justify the reduction in radiation dose as well as in, presumably, the cost of image acquisition.

The global MRI market is expected to grow to $7.5 billion by 2025, according to recent projections, up from $5.9 billion in 2017.

Clinical decision support (CDS) tools help trainee physicians in the emergency department order advanced imaging more appropriately. Then again, experienced physicians using the tools hit about the same appropriateness scores as the interns, residents and fellows.

The FDA announced Wednesday, March 27, that it is taking action to “modernize” breast cancer screening in the United States by amending the Mammography Quality Standards Act of 1992 with a new proposed rule.

Research presented at this year’s Society of Interventional Radiology conference in Austin, Texas, suggests virtual reality (VR) could be useful to interventional radiologists, improving treatments using real-time 3D images from inside a patient’s vessels.

Four years ago the U.K.’s Royal College of Radiologists released its evidence-based “iRefer” guidelines to help referring physicians in Ireland order the right imaging at the right time for the right indication. Now researchers on the Emerald Isle have compared the appropriateness of imaging ordered before and after the release, with an eye on economic costs as well as radiation doses.
